Audio Unit and Audio-Navigation Unit

An audio unit with navigation function is referred to as audio-navigation unit. This unit has built-in yaw rate sensor, an acceleration sensor, and the navigation map data is installed (refer to the Navigation System Overview).

The audio unit or the audio-navigation unit acts as the processor which includes playback functions of the AM, FM, and HD radio* tuners, the external tuner (XM*) that is connected to GA-net, the CD player, the USB, the Bluetooth audio, and the iPod for music. Select audio functions from the audio (audio-navigation) unit buttons, touch screen (Touch the display directly to select items on the screen), or the audio remote switch (on the steering wheel).

*: With navigation

The audio unit or the audio-navigation unit has a built-in EEPROM (electrically erasable programmable read-only memory). This memory holds the AM/FM audio presets (sound settings, etc.) even when the 12 volt battery is disconnected (XM presets are stored in the XM receiver).
